Description

Technical Field

[0001] The utility model relates to the technical field of power cabinets, and more specifically to an indoor cabinet with dustproof and heat dissipation function. Background Art

[0002] Power cabinets are commonly used electrical equipment in power systems, mainly used for power transmission, distribution and control. High-voltage equipment and switchgear in the power system must undergo strict electrical design and testing to ensure that they work efficiently, stably, safely and reliably. As the power system develops towards high voltage, large capacity and intelligence, the electrical design of power cabinets is becoming increasingly important. Power cabinets are divided into indoor cabinets and outdoor cabinets according to the site of use. Most of the existing indoor power cabinets use fixed panel switch cabinets, which include current transformers, voltage transformers, and high-voltage automatic reclosing sectionalizers. In order to protect these important components from being eroded by external dust particles, the components are encapsulated in a sealed metal shell, resulting in poor internal heat dissipation, affecting the normal operation of the components or even damaging them. In order to ensure good heat dissipation, other indoor power cabinets use hollow treatment at the chassis shell, so that external dust can easily enter the cabinet when the chassis is working, causing permanent damage to the cabinet. When cleaning the dust attached to the components, the cabinet needs to be disassembled and each component needs to be cleaned one by one. Some dust enters the components and cannot be removed. The structure is complex, the operation is cumbersome, and manpower is wasted. Utility Model Content
